3x-23=13
+23 +23 = add 23 to both sides when you add or subtract a positive and a negative they cancel each other out giving you 0.

3x=36

x=12 divide 3 by 3 it gives you x. divide 36 by 3 it gives you 12 therefore x=12.

That is actually in the math section not Social Studies, but I'm going to answer it anyways. What you need to do here is to leave x alone, "How do you do that?" Well, to do that you need to take out the 23 to just leave 3x alone, "How do you take out the 23?" By doing the opposite to both sides. In this case, the 23 is negative, so we add 23 to both sides. If it was positive, you subtract 23 from both sides. Now that we have added 23 to both sides, we are left with 3x=36, "What do you do now?' We still do the opposite, this time we are multiplying 3 times X, and the opposite for this is division, so we have to divide 3 to both sides to leave X alone. Now that we have divide 3 to both sides, it will leave us with X=12. YOU'RE WELCOME :)

d1i1m1o1n [39]

Answer:

a baseball tradition

Explanation:

Functionalist theorists are individuals who adopt the functionalist view to explain things around them. This view makes these theorists see the interactions of our world in a systematic way, where several factors come together, each with its function generating a stable, cohesive and efficient system. According to this point of view, a functionalist theorist would justify the baseball pitcher's incentive to "brush back" a batter who homerated on his previous bat as a baseball tradition.
